While the other penguins attempt to retrieve the ray, the down-feathered Skipper is baby-sat by Julien, under the story that he is "Petey", the penguins' cousin, much to Skipper's displeasure. After the other penguins find that the ray is in the possession of the sewer rats, they are captured by them. Sensing his team is in danger, baby Skipper slips past a sleeping Julien and enters the sewers, ultimately defeating the Rat King through quick-thinking leadership – and a flatulent emission. With the ray back in Kowalski's possession, he returns Skipper to his normal self at the HQ.
